Canon Learning Center Explains MTF Charts

Canon EF 24-105mm f/4L IS lens MTF chart

Canon Digital Learning Center has put out an interesting article on how to read and understand Modulation Transfer Function (MTF) charts. Most photography and video enthusiasts have seen these charts for different lenses, but perhaps have not been entirely clear on exactly what they communicate. We know they are supposed to give an indication of a lens’ expected optical performance, but beyond that it may be a bit of a mystery.

The article attempts to move past the technical terms and explain them in a real-world manner. Click here to read the whole article. It is worth a look to understand your equipment.
